FIELD OF THE INVENTION

This invention is directed to triazole derivatives and pharmaceutical compositions thereof which are useful as inhibitors of the receptor protein tyrosine kinase known as Axl. This invention is also directed to methods of using the derivatives and compositions in treating diseases and conditions associated with Axl activity, particularly in treating diseases and conditions associated with angiogenesis and/or cell proliferation.

BACKGROUND OF THE INVENTION

All of the protein kinases that have been identified to date in the human genome share a highly conserved catalytic domain of around 300 aa. This domain folds into a bi-lobed structure in which reside ATP-binding and catalytic sites. The complexity of protein kinase regulation allows many potential mechanisms of inhibition including competition with activating ligands, modulation of positive and negative regulators, interference with protein dimerization, and allosteric or competitive inhibition at the substrate or ATP binding sites.

Axl (also known as UFO, ARK, and Tyro7; nucleotide accession numbers NM_(—)021913 and NM_(—)001699; protein accession numbers NP_(—)068713 and NP_(—)001690) is a receptor protein tyrosine kinase (RTK) that comprises a C-terminal extracellular ligand-binding domain and N-terminal cytoplasmic region containing the catalytic domain. The extracellular domain of Axl has a unique structure that juxtaposes immunoglobulin and fibronectin Type III repeats and is reminiscent of the structure of neural cell adhesion molecules. Axl and its two close relatives, Mer/Nyk and Sky (Tyro3/Rse/Dtk), collectively known as the Tyro3 family of RTKs, all bind and are stimulated to varying degrees by the same ligand, Gas6 (growth arrest specific-6), a ˜76 kDa secreted protein with significant homology to the coagulation cascade regulator, Protein S. In addition to binding to ligands, the Axl extracellular domain has been shown to undergo homophilic interactions that mediate cell aggregation, suggesting that one important function of Axl may be to mediate cell-cell adhesion.

Axl is predominantly expressed in the vasculature in both endothelial cells (ECs) and vascular smooth muscle cells (VSMCs) and in cells of the myeloid lineage and is also detected in breast epithelial cells, chondrocytes, Sertoli cells and neurons. Several functions including protection from apoptosis induced by serum starvation, TNF-α or the viral protein E1A, as well as migration and cell differentiation have been ascribed to Axl signaling in cell culture. However, Axl−/− mice exhibit no overt developmental phenotype and the physiological function of Axl in vivo is not clearly established in the literature.

Angiogenesis (the formation of new blood vessels) is limited to functions such as wound healing and the female reproductive cycle in healthy adults. This physiological process has been co-opted by tumors, thus securing an adequate blood supply that feeds tumor growth and facilitates metastasis. Deregulated angiogenesis is also a feature of many other diseases (for example, psoriasis, rheumatoid arthritis, endometriosis and blindness due to age-related macular degeneration (AMD), retinopathy of prematurity and diabetes) and often contributes to the progression or pathology of the condition.

The overexpression of Axl and/or its ligand has also been reported in a wide variety of solid tumor types including, but not limited to, breast, renal, endometrial, ovarian, thyroid, non-small cell lung carcinoma, and uveal melanoma as well as in myeloid leukemias. Furthermore, it possesses transforming activity in NIH3T3 and 32D cells. It has been demonstrated that loss of Axl expression in tumor cells blocks the growth of solid human neoplasms in an in vivo MDA-MB-231 breast carcinoma xenograft model. Taken together, these data suggest Axl signaling can independently regulate EC angiogenesis and tumor growth and thus represents a novel target class for tumor therapeutic development.

The expression of Axl and Gas6 proteins is upregulated in a variety of other disease states including endometriosis, vascular injury and kidney disease and Axl signaling is functionally implicated in the latter two indications. Axl-Gas6 signaling amplifies platelet responses and is implicated in thrombus formation. Axl may thus potentially represent a therapeutic target for a number of diverse pathological conditions including solid tumors, including, but not limited to, breast, renal, endometrial, ovarian, thyroid, non-small cell lung carcinoma and uveal melanoma; liquid tumors, including but not limited to, leukemias (particularly myeloid leukemias) and lymphomas; endometriosis, vascular disease/injury (including but not limited to restenosis, atherosclerosis and thrombosis), psoriasis; visual impairment due to macular degeneration; diabetic retinopathy and retinopathy of prematurity; kidney disease (including but not limited to glomerulonephritis, diabetic nephropathy and renal transplant rejection), rheumatoid arthritis; osteoarthritis and cataracts.

“Prodrugs” is meant to indicate a compound that may be converted under physiological conditions or by solvolysis to a biologically active compound of the invention. Thus, the term “prodrug” refers to a precursor of a compound of the invention that is pharmaceutically acceptable. A prodrug may be inactive when administered to a subject in need thereof, but is converted in vivo to an active compound of the invention for example, by hydrolysis in blood. The prodrug compound often offers advantages of solubility, tissue compatibility or delayed release in a mammalian organism (see, Bundgard, H., Design of Prodrugs (1985), pp. 7-9, 21-24 (Elsevier, Amsterdam).

A discussion of prodrugs is provided in Higuchi, T., et al., “Pro-drugs as Novel Delivery Systems,” A.C.S. Symposium Series, Vol. 14, and in Bioreversible Carriers in Drug Design, ed. Edward B. Roche, American Pharmaceutical Association and Pergamon Press, 1987, both of which are incorporated in full by reference herein.

The term “prodrug” is also meant to include any covalently bonded carriers, which release the active compound of the invention in vivo when such prodrug is administered to a mammalian subject. Prodrugs of a compound of the invention may be prepared by modifying functional groups present in the compound of the invention in such a way that the modifications are cleaved, either in routine manipulation or in vivo, to the parent compound of the invention. Prodrugs include compounds of the invention wherein a hydroxy, amino or mercapto group is bonded to any group that, when the prodrug of the compound of the invention is administered to a mammalian subject, cleaves to form a free hydroxy, free amino or free mercapto group, respectively. Examples of prodrugs include, but are not limited to, acetate, formate and benzoate derivatives of alcohol or amine functional groups in the compounds of the invention and the like.

“Stable compound” and “stable structure” are meant to indicate a compound that is sufficiently robust to survive isolation to a useful degree of purity from a reaction mixture, and formulation into an efficacious therapeutic agent.

“Mammal” includes humans and domestic animals, such as cats, dogs, swine, cattle, sheep, goats, horses, rabbits, and the like. Preferably, for purposes of this invention, the mammal is a human.

“Optional” or “optionally” means that the subsequently described event of circumstances may or may not occur, and that the description includes instances where said event or circumstance occurs and instances in which it does not. For example, “optionally substituted aryl” means that the aryl radical may or may not be substituted and that the description includes both substituted aryl radicals and aryl radicals having no substitution.

“Pharmaceutically acceptable excipient” includes without limitation any adjuvant, carrier, excipient, glidant, sweetening agent, diluent, preservative, dye/colorant, flavor enhancer, surfactant, wetting agent, dispersing agent, suspending agent, stabilizer, isotonic agent, solvent, or emulsifier which has been approved by the United States Food and Drug Administration as being acceptable for use in humans or domestic animals.

“Pharmaceutically acceptable salt” includes both acid and base addition salts.

“Pharmaceutically acceptable acid addition salt” refers to those salts which retain the biological effectiveness and properties of the free bases, which are not biologically or otherwise undesirable, and which are formed with inorganic acids such as, but not limited to, hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid and the like, and organic acids such as, but not limited to, acetic acid, 2,2-dichloroacetic acid, adipic acid, alginic acid, ascorbic acid, aspartic acid, benzenesulfonic acid, benzoic acid, 4-acetamidobenzoic acid, camphoric acid, camphor-10-sulfonic acid, capric acid, caproic acid, caprylic acid, carbonic acid, cinnamic acid, citric acid, cyclamic acid, dodecylsulfonic acid, ethane-1,2-disulfonic acid, ethanesulfonic acid, 2-hydroxyethanesulfonic acid, formic acid, fumaric acid, galactaric acid, gentisic acid, glucoheptonic acid, gluconic acid, glucuronic acid, glutamic acid, glutaric acid, 2-oxo-glutaric acid, glycerophosphoric acid, glycolic acid, hippuric acid, isobutyric acid, lactic acid, lactobionic acid, lauric acid, maleic acid, malic acid, malonic acid, mandelic acid, methanesulfonic acid, mucic acid, naphthalene-1,5-disulfonic acid, naphthalene-2-sulfonic acid, 1-hydroxy-2-naphthoic acid, nicotinic acid, oleic acid, orotic acid, oxalic acid, palmitic acid, pamoic acid, propionic acid, pyroglutamic acid, pyruvic acid, salicylic acid, 4-aminosalicylic acid, sebacic acid, stearic acid, succinic acid, tartaric acid, thiocyanic acid, p-toluenesulfonic acid, trifluoroacetic acid, undecylenic acid, and the like.

“Pharmaceutically acceptable base addition salt” refers to those salts which retain the biological effectiveness and properties of the free acids, which are not biologically or otherwise undesirable. These salts are prepared from addition of an inorganic base or an organic base to the free acid. Salts derived from inorganic bases include, but are not limited to, the sodium, potassium, lithium, ammonium, calcium, magnesium, iron, zinc, copper, manganese, aluminum salts and the like. Preferred inorganic salts are the ammonium, sodium, potassium, calcium, and magnesium salts. Salts derived from organic bases include, but are not limited to, salts of primary, secondary, and tertiary amines, substituted amines including naturally occurring substituted amines, cyclic amines and basic ion exchange resins, such as ammonia, isopropylamine, trimethylamine, diethylamine, triethylamine, tripropylamine, diethanolamine, ethanolamine, 2-dimethylaminoethanol, 2-diethylaminoethanol, dicyclohexylamine, lysine, arginine, histidine, caffeine, procaine, hydrabamine, choline, betaine, benethamine, benzathine, ethylenediamine, glucosamine, methylglucamine, theobromine, triethanolamine, tromethamine, purines, piperazine, piperidine, N-ethylpiperidine, polyamine resins and the like. Particularly preferred organic bases are isopropylamine, diethylamine, ethanolamine, trimethylamine, dicyclohexylamine, choline and caffeine.

Often crystallizations produce a solvate of the compound of the invention. As used herein, the term “solvate” refers to an aggregate that comprises one or more molecules of a compound of the invention with one or more molecules of solvent. The solvent may be water, in which case the solvate may be a hydrate. Alternatively, the solvent may be an organic solvent. Thus, the compounds of the present invention may exist as a hydrate, including a monohydrate, dihydrate, hemihydrate, sesquihydrate, trihydrate, tetrahydrate and the like, as well as the corresponding solvated forms. The compound of the invention may be true solvates, while in other cases, the compound of the invention may merely retain adventitious water or be a mixture of water plus some adventitious solvent.

A “pharmaceutical composition” refers to a formulation of a compound of the invention and a medium generally accepted in the art for the delivery of the biologically active compound to mammals, for example, humans. Such a medium includes all pharmaceutically acceptable carriers, diluents or excipients therefor.

“Therapeutically effective amount” refers to that amount of a compound of the invention which, when administered to a mammal, preferably a human, is sufficient to effect treatment, as defined below, of a disease or condition of interest in the mammal, preferably a human. The amount of a compound of the invention which constitutes a “therapeutically effective amount” will vary depending on the compound, the disease or condition and its severity, and the age of the mammal to be treated, but can be determined routinely by one of ordinary skill in the art having regard to his own knowledge and to this disclosure.

“Treating” or “treatment” as used herein covers the treatment of the disease or condition of interest in a mammal, preferably a human, having the disease or condition of interest, and includes:

(i) preventing the disease or condition from occurring in a mammal, in particular, when such mammal is predisposed to the condition but has not yet been diagnosed as having it;

(ii) inhibiting the disease or condition, i.e., arresting its development;

(iii) relieving the disease or condition, i.e., causing regression of the disease or condition; or

(iv) stabilizing the disease or condition.

As used herein, the terms “disease” and “condition” may be used interchangeably or may be different in that the particular malady or condition may not have a known causative agent (so that etiology has not yet been worked out) and it is therefore not yet recognized as a disease but only as an undesirable condition or syndrome, wherein a more or less specific set of symptoms have been identified by clinicians.

The compounds of the invention, or their pharmaceutically acceptable salts may contain one or more asymmetric centres and may thus give rise to enantiomers, diastereomers, and other stereoisomeric forms that may be defined, in terms of absolute stereochemistry, as (R)- or (S)- or, as (D)- or (L)- for amino acids. The present invention is meant to include all such possible isomers, as well as their racemic and optically pure forms. Optically active (+) and (−), (R)- and (S)-, or (D)- and (L)-isomers may be prepared using chiral synthons or chiral reagents, or resolved using conventional techniques, such as HPLC using a chiral column. When the compounds described herein contain olefinic double bonds or other centres of geometric asymmetry, and unless specified otherwise, it is intended that the compounds include both E and Z geometric isomers. Likewise, all tautomeric forms are also intended to be included.

A “stereoisomer” refers to a compound made up of the same atoms bonded by the same bonds but having different three-dimensional structures, which are not interchangeable. The present invention contemplates various stereoisomers and mixtures thereof and includes “enantiomers”, which refers to two stereoisomers whose molecules are nonsuperimposeable mirror images of one another.

A “tautomer” refers to a proton shift from one atom of a molecule to another atom of the same molecule. The present invention includes tautomers of any said compounds.

“Atropisomers” are stereoisomers resulting from hindered rotation about single bonds where the barrier to rotation is high enough to allow for the isolation of the conformers (Eliel, E. L.; Wilen, S. H. Stereochemistry of Organic Compounds; Wiley & Sons: New York, 1994; Chapter 14). Atropisomerism is significant because it introduces an element of chirality in the absence of stereogenic atoms. The invention is meant to encompass atropisomers, for example in cases of limited rotation around the single bonds emanating from the core triazole structure, atropisomers are also possible and are also specifically included in the compounds and/or prodrugs of the invention.

The chemical naming protocol and structure diagrams used herein are a modified form of the I.U.P.A.C. nomenclature system wherein the compounds of the invention are named herein as derivatives of the central core structure, i.e., the triazole structure. For complex chemical names employed herein, a substituent group is named before the group to which it attaches. For example, cyclopropylethyl comprises an ethyl backbone with cyclopropyl substituent. In chemical structure diagrams, all bonds are identified, except for some carbon atoms, which are assumed to be bonded to sufficient hydrogen atoms to complete the valency.

The numbering system of the ring atoms in compounds of formula (Ia) and (Ib) is shown below:

For example, a compound of formula (Ia) wherein A is —C(O)—, R¹ is phenyl substituted at the 4-position by —R⁸—OR¹⁰ (where R⁸ is a direct bond and R¹⁰ is 2-pyrrolidin-1-ylethyl); R², R⁴ and R⁵ are each hydrogen and R³ is 1H-indol-5-yl; i.e., a compound of the following formula:

is named herein as 5-amino-1-(1H-indol-5-yl)carbonyl-3-[4-[2-(pyrrolidin-1-yl)ethoxy]phenylamino]-1H-1,2,4-triazole.

Utility and Testing of the Compounds of the Invention

The oncogenic RTK, Axl, was recently identified, using a retroviral-based functional genetic screening protocol, as a regulator of haptotactic migration, which is a key event in angiogenesis. Axl inhibition by RNAi-mediated silencing blocked endothelial cell migration, proliferation and in vitro tube formation. These observations, which were disclosed at the American Association Cancer Research General Meeting, Apr. 16-20, 2005, Anaheim, Calif., and The 7th Annual Symposium on Anti-Angiogenic Agents, Feb. 10-13, 2005, San Diego, Calif.; (Requirement for The Receptor Tyrosine Kinase Axl in Angiogenesis and Tumor Growth, Holland, S. J. Powell, M. J., Franci, C., Chan, E., Friera, A. M., Atchison, R., Xu, W., McLaughlin, J., Swift, S. E., Pali, E., Yam, G., Wong, S., Xu, X., Hu, Y., Lasaga, J., Shen, M., Yu, S., Daniel, R., Hitoshi, Y., Bogenberger, J., Nor, J. E., Payan, D. G and Lorens, J. B), were substantiated by an in vivo study which demonstrated that stable, shRNAi-mediated Axl knockdown impaired formation of functional human blood vessels in a mouse model of human angiogenesis. These observations were published in a peer reviewed journal (Holland S J, Powell M J, Franci C, Chan E W, Friera A M, Atchison R E, McLaughlin J, Swift S E, Pali E S, Yam G, Wong S, Lasaga J, Shen M R, Yu S, Xu W, Hitoshi Y, Bogenberger J, Nor J E, Payan D G, Lorens J B. “Multiple roles for the receptor tyrosine kinase axl in tumor formation.” Cancer Res. (2005) Vol 65 pp 9294-303. These observations are also disclosed in U.S. Published Patent Application 2005/0118604 and European Patent Application 1 563 094, the disclosures of which are incorporated in full by reference. Axl signaling, therefore, impacts multiple functions required for neovascularization in vitro, and regulates angiogenesis in vivo. Regulation of these pro-angiogenic processes required the catalytic activity of Axl. Thus, Axl-mediated angiogenic stimulation would be amenable to modulation by a small molecule inhibitor of Axl catalytic activity.

The compounds of the invention are small molecule inhibitors of Axl catalytic activity, and are therefore useful in treating diseases and conditions which are associated with Axl catalytic activity including those diseases and conditions which are characterized by angiogenesis and/or cell proliferation. Such diseases and conditions include, but are not limited to, solid tumors, including, but not limited to, breast, renal, endometrial, ovarian, thyroid, non-small cell lung carcinoma and uveal melanoma; liquid tumors, including but not limited to, leukemias (particularly myeloid leukemias) and lymphomas; endometriosis, vascular disease/injury (including but not limited to restenosis, atherosclerosis and thrombosis), psoriasis; visual impairment due to macular degeneration; diabetic retinopathy and retinopathy of prematurity; kidney disease (including but not limited to glomerulonephritis, diabetic nephropathy and renal transplant rejection), rheumatoid arthritis; osteoarthritis and cataracts.

Surfactants are compounds that non-covalently interact with the compound of the invention so as to facilitate dissolution or homogeneous suspension of the compound in the aqueous delivery system.

The compounds of the invention, or their pharmaceutically acceptable salts, are administered in a therapeutically effective amount, which will vary depending upon a variety of factors including the activity of the specific compound employed; the metabolic stability and length of action of the compound; the age, body weight, general health, sex, and diet of the patient; the mode and time of administration; the rate of excretion; the drug combination; the severity of the particular disorder or condition; and the subject undergoing therapy. Generally, a therapeutically effective daily dose is (for a 70 kg mammal) from about 0.001 mg/kg (i.e., 0.7 mg) to about 100 mg/kg (i.e., 7.0 gm); preferably a therapeutically effective dose is (for a 70 kg mammal) from about 0.01 mg/kg (i.e., 7 mg) to about 50 mg/kg (i.e., 3.5 gm); more preferably a therapeutically effective dose is (for a 70 kg mammal) from about 1 mg/kg (i.e., 70 mg) to about 25 mg/kg (i.e., 1.75 gm).

Compounds of the invention, or pharmaceutically acceptable derivatives thereof, may also be administered simultaneously with, prior to, or after administration of one or more other therapeutic agents. Such combination therapy includes administration of a single pharmaceutical dosage formulation which contains a compound of the invention and one or more additional active agents, as well as administration of the compound of the invention and each active agent in its own separate pharmaceutical dosage formulation. For example, a compound of the invention and the other active agent can be administered to the patient together in a single oral dosage composition such as a tablet or capsule, or each agent administered in separate oral dosage formulations. Where separate dosage formulations are used, the compounds of the invention and one or more additional active agents can be administered at essentially the same time, i.e., concurrently, or at separately staggered times, i.e., sequentially; combination therapy is understood to include all these regimens.

Preparation of the Compounds of the Invention

The following Reaction Schemes illustrate methods to make compounds of this invention, i.e., compounds of formula (Ia) and compounds of formula (Ib):

where A, R¹, R², R³, R⁴ and R⁵ are described above in the Summary of the Invention, as isolated stereoisomers or tautomers thereof or mixtures thereof, or as pharmaceutically acceptable salts, hydrates, solvates, N-oxides or prodrugs thereof. It is understood that in the following Reaction Schemes, combinations of substituents and/or variables of the depicted formulae are permissible only if such contributions result in stable compounds.

It will also be appreciated by those skilled in the art that in the processes described below the functional groups of intermediate compounds may need to be protected by suitable protecting groups. Such functional groups include hydroxy, amino, mercapto and carboxylic acid. Suitable protecting groups for hydroxy include trialkylsilyl or diarylalkylsilyl (for example, t-butyldimethylsilyl, t-butyldiphenylsilyl or trimethylsilyl), tetrahydropyranyl, benzyl, and the like. Suitable protecting groups for amino, amidino and guanidino include t-butoxycarbonyl, benzyloxycarbonyl, and the like. Suitable protecting groups for mercapto include —C(O)—R″ (where R″ is alkyl, aryl or arylalkyl), p-methoxybenzyl, trityl and the like. Suitable protecting groups for carboxylic acid include alkyl, aryl or arylalkyl esters.

Protecting groups may be added or removed in accordance with standard techniques, which are known to one of ordinary skill in the art and as described herein.

The use of protecting groups is described in detail in Green, T. W. and P. G. M. Wuts, Protective Groups in Organic Synthesis (1999), 3rd Ed., Wiley. As one of skill in the art would appreciate, the protecting group may also be a polymer resin such as a Wang resin, Rink resin or a 2-chlorotrityl-chloride resin.

It will also be appreciated by those skilled in the art, although such protected derivatives of compounds of this invention may not possess pharmacological activity as such, they may be administered to a mammal and thereafter metabolized in the body to form compounds of the invention which are pharmacologically active. Such derivatives may therefore be described as “prodrugs”. All prodrugs of compounds of this invention are included within the scope of the invention.

It is understood that one of ordinary skill in the art would be able to make the compounds of the invention by methods similar to the methods described herein or by methods known to one of ordinary skill in the art. It is also understood that one of ordinary skill in the art would be able to make in a similar manner as described below other compounds of formula (Ia) and formula (Ib) not specifically illustrated below by using the appropriate starting components and modifying the parameters of the synthesis as needed. In general, starting components may be obtained from sources such as Sigma Aldrich, Lancaster Synthesis, Inc., Maybridge, Matrix Scientific, TCI, and Fluorochem USA, etc, or synthesized according to sources known to those skilled in the art (see, for example, Advanced Organic Chemistry: Reactions, Mechanisms, and Structure, 5th edition (Wiley, December 2000)) or prepared as described in this invention. ¹H NMR spectra were recorded in CDCl₃, DMSO-d₆, CD₃OD, Acetone-d₆ with trimethylsilane (TMS) as internal reference using Gemini 300 MHz instrument. Reagents and solvents were purchased from commercial sources and used without further purification. Flash column chromatography was conducted using silica gel (230-400 mesh) under a positive pressure of nitrogen. LCMS spectra for purity and mass were recorded using Waters LCMS instruments. Deionized water was used to dilute the reactions and wash the products. Brine used was prepared by dissolving sodium chloride into deionized water to saturation point.

In general, diphenylcyanocarbonimidate 1 (1.1 equiv) and appropriately substituted aniline 2 (1 equiv) are stirred in isopropyl alcohol at ambient temperature overnight. The diarylisourea product, 3, generally precipitates and isolation can be accomplished via filtration, washing with an appropriate solvent, and drying. Hydrazine hydrate (2 equiv) is added to a slurry of 3 in an alcohol or other appropriate solvent. Generally, the ring formation reaction occurs at ambient temperature and the product triazole, 4, can be isolated by standard isolation techniques. The 3,5-diamino-1,2,4-triazole, 4, is then acylated with an appropriately substituted benzoic acid 5 to provide a mixture of the acylated products, (Ia-1) and (Ib-1), which can be separated and isolated by standard separation and isolation techniques, such as chromatography.

Compounds (Ia-2), as set forth below in Reaction Scheme 1A, are compounds of formula (Ia), as set forth above in the Summary of the Invention, and are prepared as illustrated below in Reaction Scheme 1A. For purposes of convenience, the minor product, i.e., the corresponding compound of formula (Ib), is not illustrated in Reaction Scheme 1A, but it is understood that the compound is prepared as well by the method disclosed therein and is isolated and separated from compound (Ia-2) by standard isolation and separation techniques.

Specifically, diphenylcyanocarbonimidate 1 (1.1 equiv) and aniline 2a (1 equiv) were stirred in iso-propyl alcohol at ambient temperature overnight. The white precipitate was filtered and washed with iso-propyl alcohol and dried to yield 3a. Then hydrazine hydrate (2 equiv) was added to a slurry of 3a in methanol. After stirring at ambient temperature overnight the solution was concentrated and the oily residue was triturated with diethyl ether to remove impurities and give 4a as a white solid. The 3,5-diamino-1,2,4-triazole compound 4a was then acylated with benzoic acid 5a mediated by HOAt/EDCl.HCl and ^(i)Pr₂NEt in anhydrous DMF. The reaction mixture was diluted with ethyl acetate and washed with aqueous sodium bicarbonate. The organic layer was separated and concentrated. Purification of the residue by silica gel column chromatography in 5% triethylamine/ethyl acetate gave 5-amino-1-(4-(iso-propoxy)phenyl)carbonyl-3-[4-[2-(pyrrolidin-1-yl)ethoxy]phenylamino]-1H-1,2,4-triazole (Ia-2), as a yellow solid (38% yield); ¹H-NMR (DMSO-d₆, 300 MHz) 9.01 (s, 1H), 8.22 (d, J=8.7 Hz, 2H), 7.69 (br. s, 2H), 7.41 (d, J=8.7 Hz, 2H), 7.04 (d, J=8.7 Hz, 2H), 6.82 (d, J=8.7 Hz, 2H), 4.78 (m, 1H), 3.98 (br. s, 2H), 2.77 (br. s, 2H), 2.48 (m, 4H), 1.67 (m, 4H), 1.30 (d, J=6.0 Hz, 6H) ppm; MS (ES) 451.4 (M+H), 449.0 (M−H).

Methods: Day 1:

A 96 well TC (tissue culture treated) plate was coated with 10 μg/mL poly-L-Lysine at 37° C. for 30 min, washed twice with PBS, and air-dried for 5 minutes before cells were added. Hela cells were seeded at 10,000 cells/well and the cells were starved in 100 μL starvation medium containing Axl/Fc for 24 hrs.

Day 2:

The cells were pre-treated with test compounds by adding 100 μL of 2× test compound to the starvation medium on the cells. The cells were incubated at 37° C. for 1 hr before stimulation.

The cells were stimulated by Axl-antibody cross-linking as follows: A 5×1^(st)/2^(nd) Axl antibody mixture was made (37.5 μg/mL 1^(st)/100 μg/mL 2^(nd)) in starvation medium and nutated at 4° C. with thorough mixing for 1-2 hours for clustering. The resulting mix was warmed to 37° C. 50 μL of 5× Axl 1^(st)/2^(nd) of antibody cluster was added to the cells and the cells were incubated at 37° C. for 5 min.

After 5 minutes stimulation, the plate was flicked to remove medium and the plate was tapped onto paper towels. Formaldehyde (4.0% in PBS, 100 μL) was added to fix the cells and the cells were incubated at ambient temperature for 20 min without shaking.

The cells were washed with a plate washer buffer to remove the formaldehyde solution. The plate was flicked to removed excess wash buffer and tapped onto paper towels. Quenching buffer (100 μL) was added to each well and the cells were incubated at ambient temperature for 20 minutes without shaking.

The cells were washed with a plate washer buffer to remove the quenching buffer. Blocking buffer (100 μL) was added and the cells were incubated at ambient temperature for at least an hour with gentle shaking.

The cells were washed with a plate washer buffer and diluted primary antibody (50 μL) was added to each well (blocking buffer was added to the negative control wells instead). The plates were incubated overnight at 4° C. with gentle shaking.

Day 3:

The wash buffer was removed, diluted secondary antibody (100 μL) was added, and the cells were incubated at ambient temperature for 1 hour with gentle shaking. During the incubation, the chemiluminescent reagent was brought to ambient temperature.

The secondary antibody was removed by washing the cells 1× with wash buffer, 1× with PBS by plate washer. The PBS was removed from the plate and the chemiluminescent reagent (80 μL: 40 μL A and 40 μL B) was added to each well at ambient temperature.

The resulting chemiluminescence was read with a Luminomitor within 10 minutes to minimize changes in signal intensity. After reading the chemiluminescence, the cells were washed 1× with wash buffer and 1× with PBS by plate washer. The plate was tapped onto paper towels to remove excess liquid from wells and air-dried at ambient temperature for 5 minutes.

Crystal Violet working solution (60 μL) was added to each well and the cells were incubated at ambient temperature for 30 min. The crystal violet solution was removed, and the wells were rinsed with PBS, then washed 3× with PBS (200 μL) for 5 minutes each.

5% SDS solution (70 μL) was added to each well and the cells were incubated on a shaker for 30 min at ambient temperature.

The absorbance was read at 590 nM on a Wallac photospec. The 590 nM readings indicated the relative cell number in each well. This relative cell number was then used to normalize each luminescence reading.
